const size_t blaze::solvers::maxIterations = 25000
 Maximum number of iterations of the mathematical solvers.This value specifies the default maximum number of iteration steps the mathematical solvers are performing for a single LSE or LCP problem. The choice of the number of iteration steps is a consideration between the accuracy of the solution and the time to solution: for a large number of iteration steps, the solution will be more accurate, whereas a small number will be considerably faster to calculate. For instance, an important property of the PGS solver is that the convergence speed of the approximated solution is strongly decreasing with a larger number of time steps. In order to noticeably improve the solution, the maximum number of time steps has to be considerably increased.
 
const real blaze::solvers::threshold = 5E-7
 Residuum threshold for the LSE/LCP solution of the mathematical solvers.This value specifies the threshold for the residuum calculation during a solution of a single LSE or LCP problem. The calculation stops as soon as the approximated solution meets the specified threshold value. The choice of the threshold value is a consideration between the accuracy of the solution and the time to solution: for a small threshold value (e.g. $ 1e-9 $), the solution will be more accurate, whereas a large threshold value (e.g. $ 1e-5 $) will be considerable faster. For instance, an important property of the PGS solver is that the convergance speed of the approximated solution is strongly decreasing with a larger number of time steps. The time to solution for a LCP calculation using a smaller threshold value will be noticeably larger.
